Serious Brake Upgrade

As part of our track testing and development of GTR parts at Willall Racing one thing we have done is overpowered the standard braking system. In 12,000 miles we have exhausted 5 sets of brake rotors and around 15 sets of brake pads, and in the middle developed a water cooling system - WR35WS - which has helped us and many others around the world keep a longer and stronger pedal and nearly double pad life. The problem being - the faster you go and the better tyre you have, the more brake you need....

We chose the Endless braking system for R35 for a couple of reasons. Firstly we needed a stiffer and stronger caliper. We were losing 30% of pad life at least with the taper - in both axis - in pad wear with the standard caliper. Secondly Endless offer a bigger rotor, titanium piston, and super thick (double the thickness of stock GTR) brake pads. Its part of their Super Taikyu endurance program, so lets get them on....

This weekend we are testing at the track. We have an existing benchmark with the stock braking system on AP J-Hooks/stock calipers, we are using the same Advan 20 inch slick tyre set, and the weather conditions look to be similar. Yes we have developed a WR35WS water injection setup for these bad boys as well. In my experience on the matter, nothing suits a race track better than a race brake...and I cant wait to put this Endless Mono-6 setup to the test and see how it stacks up against the Brembo competition setup on our Porsche GT Car :cheers:

wow, massive number of vanes in those rotors! I'm guessing they pump a fair bit of air.

the calipers looks nice and very 'reminiscent' of alcon and the current generation brembos... even the font is very brembo...

yeah nothing adds confidence like brakes that perform stop after stop.

84 vane rotors.

Combined with our water injection system they should be the business :)

(I have always loved Endless gear, it just works so well)

New Endless Mono-6 system was awesome at EC :)

As for the water? It turns to steam before it really even contacts the rotor so there is no evidence it has even been there apart from a very cool rim (or at least not red-hot) when the car comes back into the pits....

Will check on the piston area with Endless.

Hello Martin. Is this the same as the kit developed for the HKS R35 GTR? Looks very similar. Also didn't I read somehwere you had already done a ceramic brake upgrade instead?

Cheers

If you have the OEM Brembo calipers there that is piston area I would like to know... thanks Martin.

Good to hear they worked well :)

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
